“…The fact that this broad emission results from 1020 nm excitation is also important because previous reports of lasing in Bi doped glasses tend to come from long excitation wavelengths. For example, the excitation wavelengths of various Bi doped glass lasers are: 1070 nm [31], 1080 nm [32] and 1205 nm [33]. The QE at 1020 nm excitation is ~17% which compares favorably to the 11% QE reported for Bi doped alumino-silicate glass [34].…”

Abstract:We report emission from a bismuth doped chalcogenide glass which is flattened, has a full width at half maximum (FWHM) of 600 nm, peaks at 1300 nm and covers the entire telecommunications window. At cryogenic temperatures the FWHM reaches 850 nm. The quantum efficiency and lifetime were as high as 32% and 175 µs, respectively. We also report two new bismuth emission bands at 2000 and 2600 nm. Absorption bands at 680, 850, 1020 and 1180 nm were observed. The 1180 nm absorption band was previously unobserved. We suggest that the origin of the emission in Bi:GLS is Bi 45-50 (1996). 36. J.

“…Интерес к таким материалам связан с возможностью их использования для создания лазеров в указанном диапазоне длин волн и для усиления оптических сигналов в диапазоне 1300-1500 нм для волоконных систем связи следующего поколения. До настоящего времени лазерная генерация и оптическое усиление на волоконных световодах, легированных висмутом, получены в области длин волн 1150-1550 нм [1][2][3][4][5][6][7][8]. Серьезным препятствием на пути совершенствования висмутовых лазеров и усилителей является отсутствие адекватной модели ИК висмутового активного центра (BAC) в оптических средах.…”
